6 EXAMINATION (Continrid) 7 BY MR. GLASSMAN:

l l

8 Q

Mr. LaBelle, I would like you to focus 9

again on GPU Exhibit-286 marked for identification.

i Ib The last full paragraph beginning with the words 4

1 l{

11 "As Safety Analysis proceeds," contains a reference to h

12 an interface structure.

13 Can you tell us what you had in mind in 14 using those terms?

15 A

The units listed here interface with each other.

i l

16 Q

How was the build-up of an interface

[

17 structure between the various units as reflected in l

18 this memorandum different from the structure as it b

19 existed before that time?

i 20.

A Just in terms of the amount of work activity.

l s

21 Q

The second sentence of that paragraph I

22 says that i

23

"... there is the potential for confusion 24 over work responsibilitie-, cost recovery and i

25 work control."

j h

I.

1 LaBelle.

132 2

Why was there a potential for confusion 3

ver work responsibilities?

4 A

I think the reference is more to awareness by 5

those organizations in their interfacing of the work 6

that was being conducted.

7 Q

Had there been any prior confusion over l

8 work responsibilities?

I 9

A No, sir.

10 Q

That paragraph ends with the sentence:

i 11 "I

therefore request that you please

}

12 review our recommendations...."

13 To what recommendations were you referring Ok,)

14 in that sentence?

15 A

Not having complete recall of the recommendations i

16 that are suggested here, I can only accept what is 17 stated here in the memo,which are the activities that L

18 are prescribed in A, B and C and the attached 19 recommendations of Mr. Vosburgh and Mr. Bonoca.

20 Q

Did you receive directional input from 21 Dr. Roy or Dr. Womack in reLpons2 to your request?

22 A

I have no recollection that that took place.

23 Q

I would like to refer to the next page of f

24 GPU Exhibit-286 marked for id en tifit:a tion, which is page-I (tqcSoD l

first pageAof the May 1, 1979Aattachment from Mr.

2 vosburgh and Mr. Bonoca to yourself.

The second full (fGW$0

~

3 paragraph rea s as follows:

4 4

"Our opinion is that the following recommendations are of extreme importance 5

I i

and should receive Enginearing Department 6

7 attention to provide the impetus for their 8

implementation."

9 Did you agree with that recommendation 10 in that statement?

11 A

At the time that this information was forwarded 12 to Dr. Womack and Dr. Roy I had at least in principal

(

13 indicated the importance of the information, not 14 necessarily.the extreme importance of the information.

15 Q

To whom had you indicated the importance 16 of that information?

17 A

Just in the fact that this information was 18 escalated to my. superiors.

19 Q

The next paragraph of the May 1st, 1979A 905o7) 20 attachment to your May 7th, 197 memo refer to as l

21

"... comprehensive safety evaluation of i

22 the 177-FA plants based on event tree 23 evaluations, and not strictly on licensing l

24 requirements."

2' 25 How did such a program differ from what

!O b

1 LaBelle 134 had been done before?

2 fj}@

(O) s/

A The Safety Analysis ReportAcontained licensing 3

4-guidelines provided by the Nuclear Regulatory Nh cmaissio(qgforassumptionsandpresentationofmaterials 5

6 supporting transient and accident sequences.

i l

7 Q

Were event tree evaluations used by q)y)1 (9903AS) 8 Prior to the TMI-2.accideng?

A While I was unit manager of Safety Analysis we 9

did not utilize event tree evaluations.

10 11 Q

'Were event tree evaluations techniques i

12 known to you during the period you were manager of the 13 safety. Analysis Unit and prior to the TMI-2 accident?

()

14 A

Yes, sir.

15 Q

Why were they not used at that time?

16 A

This was not a normal practice within the unit 17 at that time.

18 Q

Why was it not a normal practice within 19 the unit at that time?

20 A

The transient and accident analysis were based l

21 upon licensing guidelines that had previously been 22 established.

J 23 Q

Is there any other reason why event tree 24 evaluations were not used prior to the TMI-2 25 accident?

A b

LaBalle 135 2

A No, sir.

3 Q

Have event tree evaluations been used by TMI-2 acciden(t?99n3p8) 4 S[M[$ subsequent to the g

i 5

A Yes, sir.

4 6

Q Are event tres evaluations now required

{

7 by NRC licensing guidelines?

8 A

I do not know.

i 9

Q Do you know of.any such licensing l

1 10 guidelines requiring event tree evaluations?

3 11 A

I have no recollection of those, no, sir.

11 I

12 Q

. Wh'y are event tree evaluations now used 13 by,B & W7

()

14 A.

I have no specific recollection as to why they 4

15 are being used presently.

4 16 Q'

What is their function?

4 17 A

To better understand the overall component and i

18 system response.

{

19 Q

Is it correct to say that event tree i

)

20 evaluation now provides a better understanding of i

3 21 system response than existed within B & W prior to the J

F 22 TMI-2 accident?

u A

I could not say with assurety that that is t r u e",

4 24 no, sir.

I 25 Q

Do you have an opinion on the subject?

ii t

7-1 LaBelle 136 O.

2 MR. WISE:

I am going to object to that.

I d n't think his opinions are relevant or 3

5 4

helpful on a question of that nature following the accideng(ynosasO l

$P 5

MR. GLASSMAN:

Mr. LaBelle is director of 6

7 Safety. Analysis or at least was at certain 8

times after the accident and he can answer the 9

question.

i 10 MR. WISE:

He st.id h3 doesn't know.

What 11 you are really,doing is asking him to guess or 12 speculate.

13 MR. GLASSMAN:

He said he didn't know with

)

14 certainty,or assurety or something to that 15 effect.

16 MR. WISE:

I think you have asked the 17 question as to whether it did or did not.

He i

18 told you he doesn't know.

To then go further i

19 and ask him for an opinion is essentially asking 20 the same question again hoping to get a 21 different answer.

I don't think it is proper.

i 22 I object to the' form of the question and 23 if the witness wants to venture an answer I f

l 24 suppose he can.

I will not direct him not to l

/s s-25 answer.

e Y

A

l 1

LaBolle 137 1

l (3) 2 I think the question is improper and I 3

don't think it is valuable given his previous 4

answer.

5 BY MR. GLASSMAN:

I 6

Q Mr. LaBelle, will you please answer the i

7 question?

8 THE WITNESS:

Will you repeat the question, l

P ease?

9 10 (The pending question was read by the j

l 11 reportar.)

12 A

No, sir.

13 Q

Mr. LaBelle, have event tree analyses (190%C 14 subsequent to the TMI-2.-accident related to sequences A

(

(S0b J

15 of eventsAthat were not analyzed prior to the TMI-2 a

16 accident?

17 A

I do not understand the sequence of events that 18 you are referring to.

f 19 Q

Have any sequences of events been analyzed

21 TMI-2 accident which event or sequence of events had h

If you wanted to. find out, who in %3(]R

+

6 would you ask?

f 7

A The individuals that are involved in the (AT~o&)

the B & W owners group.

Which individuals are they?

d 12 Q

Under the heading " Event Tree Simulation" (W W 1979 memo contained in GPU Exhibit-273 13 on the May 1, A

)

14 marked for identification, the lead unit is indicated 15 as being Safety Analysis /ECCS.

16 Does that mean . sat there were two lead 17

' units?

18 MR. WISE:

Excuse me.,

You are now speaking 19 about the recommendations that Mr. Vosburgh and 20 Mr. Bonoca were making or are you speaking about 21 something that in fact happened?

It is unclear 22 from your question.

23 MR. GLASSMAN:

Mr. Wise, I don't think we 24 need your input on what this means.

I think I 25 was very plainly asking a question regarding the e

m I

1 LaBelle 139 I

'fhDIO s

2 May 1, 1979 memorandun..

A 3

I d n't think that the witness needs any 4

more coaching from you as to the nature of the 5

memorandum.

l 6

MR. WISE:

I object to that, Mr., Glassman, I

7 and it's been a continual thing with you that 8

every. time an objection is made you accuse 9

opposing counsel of. coaching.

10 Your questien is improper in form and I 4,

11 direct him not to ancwer.it and let's go ahead.

)!

12 If you want to proceed that way -- and I thought 13 I was trying to help by clarifying the situation

()

14 so that you could proceed.

15 If.you want to play lawyer, we can do it 4

16 that way, too.

t 17 MR. GLASSMAN:

I don't know how my question 18 could be clearer.

j 19 MR. WISE:

It is improper.

It assumes 20 facts 'not in evidence, and I can support that I 21 think if you want to have the record repeated.

22 Your choice of verbs indicated a fact.

That 23 fact has not been established.

i 18 MR. WISE:

I will permit him to answer to 19 the extent he has an understanding.

I object 20 to the form of the question on any other basis.

This is a reference to the existing Safety 22 Analysis Report analysis.

In what respect might the bounding SAR

I do not know.

LaBelle 143 2

Q What was your understanding of why this 3

capability must lie in the Safety Analysis area?

4 A

As I mentioned previously, I have no opinion to

5 offer in that area.

i 6

Q What was your understanding?

7 MR. WISE:

His understanding of what?

He 8

said he had no opinion.

9 MR. GLASSMAN:

I didn't ask that question.

10 Perhaps the reporter can read back the I

11 question.

12 (The question referred to was read by the 13 reporter as requested.)

14 MR. WISE:

What was his understanding of 15 what?

16 THE WITNESS:

Could you go back several i

17 questions?

18 MR. WISE:

Let him rephrase the question.

I 19 MR. GLASSMAN:

I think I will put it back 20 on the record so the record is clear, Mr.

(

21 LaBelle.

1 22 BY MR. GLASSMAN:

23 Q

What was.your understanding, sir, of why 24 this capability must lie in the safety Analysis area?

25 MR. WISE:

I object.

Can we have the t-i

I 2

reporter read back the question two before?

I think it is the exact same question.

3 4

MR. GLASSMAN:

That.was precisely what I 5

wanted to do to make sure we have the proper 6

question on the record before the witness.

l 7

(The record was read by the reporter as 8

requested.)

9 MR. WISE:

While we were off the record i

I' 10 we have had the question reread.

It is the i

11 identical question which Mr. LaBelle already 12 answered by.saying he doesn't have an opinion.

l I

13 Counsel indicated he wanted to make sure

7.,

' )

14 that Mr. LaBelle in his answer is also including 15 whether he has an unders.tanding besides an 16 opinion.

17 To that extent, I will permit Mr. LaBelle i

18 to clarify' whether in his previous answer he 19 meant to include a laux of understanding as well 20 as a lack of opinion.

21 A

Before I provide a response it would be helpful 22 to me to understand what was meant by " capability" in 23 your question.

24 Q

Did you understand that a capability to

25

" evaluate all branches of event trees to assure bounding

to a limiting situation," that such a capability must 4

r should lie in the Safety Analysis area?

5 I

6 A

The entire capability.should not exist in the j

7 Satsty A'nalysis Unit.

(

8 Q

Why could it not exist in the Safety 9

Analysis Unit?

10 A

To the extent of understanding the entirety 11 of system -- systems interaction and operator 12 effects, also to the extent of the responsibilities 13 that the unit had for certain transient and accidents >-

(

14 transients and accidents.

15 Q

Did Messrs. Vosburgh and Bonoca communicate 16 to you in words or substance a recommendation that the 17 entire capability should lie in the Safety Analysis 18 area?

19 A

No, sir.

20 Q

What capability did you understand Messrs.

21 Vosburgh and Bonoca to be referring to in this paragraph (MosoQ 22 on Page-2 of the May 1, 197,9 memorandum?

4 23 A

You keep referring to capability.

Capability 24 for what purpose is where I have difficulty in trying

's 25 to recall their interest at the time this particular L

t.

1 LaBolle 146 N

2 memo was issued.

3 Q

At or about the *:ime this memo was issued 4

did you feel that the responsibilities of the Safety S

Analysis Unit should be expanded?

I 6

A If the activity. suggested here was to be i

7 Performe~d within the unit,yes, sir.

Make that safety

8 Analysis Unit.

9 Q

Do you know if.the recommendation

{8 0501) 10 contained in Phase-3 on Page-2 of the May 1, 1979A 11 memo was ever carried out in whole or in part?

12 A

No, sir.

13 Q

Under the heading " Computer Code s

14 Modifications and Devel'opment" further on on this r

15 Page, the paragraph.begins with the statement:

16 "The current versions of CADDS and TRAP-A fare adequate for licensing type analyses..."

17 18 Can you tell us what TRAP 2 is?

i 19 A

TRAP 2 is a CRAFT code derivitive with a more

$Y 20 detailed steam generatorgmodel.

1 l

21 Q

Do you know what the acronym TRAP stands t

22 for?

l 23 A

I just cannot recall, sir.

24 Q

Did you agree that the current versions e

i 25 of CADDS and TRAP 2 were adequata for licensing type

' V t

4

]

1 LaBelle 147 2

analyses?

w A

These codes were adequate to the extene that 3

4 they had been accepted by the Nuclear Regulatory commission (N Afor performance of accidents and transient 5

i e nditions which the safety Analysis Unit was i

6

' 1, j

y responsible for in preparation of the accident

'l 8

analysis section of the Safety Analysis Report.

l 9

Q Is there any respect in which the current 10 versions of the CADDS and TRAP =4 were inadequate for

,i 11 licensing-type analyses?

i i

12 A

They were adequate to the extent of application 13 for which they. ware licensed by the Nuclear

()

14 Regulatory Commission for transient and accident 15 analysis.

i 16 Q

The same sentence of GPU Exhibib-273 17 marked for identification continues with the statement 18 that:

j 19

"...they are not adequate for more 20 complex or ' realistic' situations."

1 21 Do you agree with that statement?

4 l

22 A

I do not know what the author's interpretation 23 of " complex" might have referred to.

In terms of 24 realistic analysis, I would concur with that t

25 particular statement.

e-

~ -

1 LaBelle 148 2

Q What do you mean by the term " realistic" 3

in this context?

4

-A These codes were for licensing-type analyses 5

and were not designed for operational-type analyses.

,t 6

Q What is the difference between licensing-7 type analyses and operational-type analyses?

[

I l

8 A

Licensing-type analyses would refer to the t

conservative or bounding-type an.. lysis provided in the 9

(SA0 safety. Analysis ReportA or the accident and transient -

f 10

.I 11 analysis.

4 12 Q

How does that differ from operational-type 13 analyses?

14 A

Operational analyses-is just that, the functioning 15 of each piece of equipment in accordance with its 1

(

16 normal operation.

17 Q

Is that based on actual operating

~

t 18 experience?

i 19 A

I do not understand what you mean in terms of 20 "is that based on."

i 21 g

what is meant by the term " normal 22 operation" when you speak of the functioning of each l;

l I

1 23 piece of equipment in accordance with normal operation?

24 MR. WISE:

Do you want him to define the 25 words " normal operation" for you?

4 1

)

1 LaBello 150 2

Q Have you seen any approval letter from O

the NRC on those codes?

3 4

A It is possible that I have, but not that I can

t 5

recall having seen.

i'I 6

Q If you wanted to find such letters if they

,(

7 existed *would you also go to the licensing group?

8 A

Yes, sir.

l 9

Q Further on in the same paragraph there is 10 a reference to " department level priority."

What does i

4' 11 that mean?

1 12 A

That.is in the sentence:

"These mods will be 13 requested..."?

l

)

14 Q

Yes, that is. correct.

15 THE WITNESS:

Okay.

Could you repeat that 16 question for me, please?

17 (The pending question was read by the 1

18 reporter.)

19 A

Department level would refer to the engineering 20 department and that these code changes for development 21 of operational models would receive priority at that 22 engineering department level.

i 23 Q

Do you agree that these program mods will i

24 be required regardless of future user's group work?

25 A

You are referring here to the words in the next l

LaBelle 149 2

MR. GLASSMAN:

Yes, as he understands it 3

in this context.

4 A

It is the way that the equipment operates.

NRC7 7

A As far as I know it is.

What is the basis of your knowledge?

The code has been used in previous SAR 10 licensing efforts and those Safety, Analysis Reports l

11 have been licensed.

12 Q

Is there an'y.other basis for your 13 statement?

(D

\\s /

14 A

There could be a concurrent letter to ([MCN 15 stating the acceptance of the code for licensing by 16 the Nuclear Regulatory Commissions 4

17 Q

Have you ever seen s"ch a letter?

Not that I can recall.

j 19 Q

If you ' wanted to find such a letter f

20 where would you look?

No, sir.

12 be required regardless of future user's group work?

13 MR. WISE:

I think in fairness to the 4

')

1<

record we ought to have the whole sentence put J

15 in just so that someone reading this knows what 16 it is we are talking about, since there have i

17 been several references to parts of this 18 sentence.

i 19 The sentence in its entirety reads:

20 "From current NRC analysis requests, these 4

21 program mods will be required regardless of future 22 user's group work."

23 BY MR. GLASSMAN:

I think in reading the sentence that if the

in keeping with my particular feelings at that time.

If the program mods were required or micht 5

be required regard 1ess of future user's group work, i

6 does that mean that $3(]Fwouldpay for the program

8 A

I could not say at a11 with respect to that.

9 Q

I would like you to refer to the next page 10 of GPU Exhibit-273 marked for identification under 1

21 more complex than operators had aeen led to believe?

this sen'tence?

12 been led to believe that event diagnosis is

13 more complex -- excuse me; just let me restate 1 ( ),

/'

14 that.

%d 15 That became slightly garbled.

I think 16 the question was probably clearer at the 17 beginning, but I will restate it.

18 MR. WISE:

19 that we are having a little difficulty figuring l

20 out what it is now leads me to believe it should

Was this an accurate reflection of your

I 12 A

Since I wrote it at that time I would presume 13 that it is.

I.4 Q

In what respect were operators not prepared 15 to cope with abnormal operating conditions which do 16 not align closely.with anticipated and design basis 17 conditions?

18 A

The fact that the TMI-2 incident had occurred.

Was B[hCN familiar with abnormal operating 20 conditions which did not align closely with anticipated i

21 and design basis conditions?

22 MR. WISE:

Was B & W familiar?

2 A

It's a very general statement.

I don't know U

that I could answer it.

3 4

Q Mr. LaBelle, at the time you prepared 5

GPU Exhibit-287 marked for identification were you 6

aware of any.. abnormal operating conditions at TMI-2 g

7 which did not align closely.with anticipated and l

8 design basis conditions?

9 THE WITNESS:

Could you repeat the i

10 question, please?

l 11 (The pending question was read by the 12 reporter.)

13 A

No, sir.

14 Q

What was the basis of your statement that 15 operators are not prepared to cope with abnormal 16 operating conditions whic.h do not align closely.with 17 anticipated and design basis conditions?

18 A

As I mentioned earlier, the fact that the TMI-2 19 incident had occurred.

I 20 Q

What aspect of the TMI-2 accident did not 21 align closely with anticipated and design basis g

1 22 conditions?

i 23 A

The overall combination of events that occurred 24 had not previously been included in the Safety Analysis

To the sequence of event =A that occurred during 5

the TMI-2 incident.

6 Q

What sequence of events are you referring i

l q

to?

I 8

A The sequence of events.

l' Q

Can you tell us the sequence of events that 9

10 you have in mind so that it is clear on the record?

l 11 A

There were several sequence of events which were 12 prepared, all of which seemed to have general agreement l

l,r g 13 to my recollection.

These sequence of events were It l

~#

14 submitted by GPU, B[)CW and the Nuclear Regulatory h

15 Commissiongand perhaps others.

16 Q

Did the sequence of events include multiple 17 failures?

18 A

I cannot recall that ! c di t.

I will' qualify that 19 by saying it is a matter of what is meant by " multiple 20 failures."

I am aware of an event at the Davis-Besse plan't t

6 which included part of the sequence which you 7

mentioned.

8 Q

Which part of.the sequence did it include?

9 A

That there was an open PORV-type transient.

10 Q

Was the possibility,of a stuck-open PORV 11 ever referred to or included in the safety Analysis h

12 13 MR. WISE:

May,I have that repe'ated, l

P ease?

14 15 (The pending question was read. by.the 16 reporter.)

17 A

The particular occurrence of a stuck-open PORV 18 was not an event of which the Safety Analysis Unit 19 was responsible.

~ 20 Q

Regardless of whether or not this was the 21 Safety. Analysis Unit's responsibility, was the 22 occurrence of a stuck-open PORV referred to or 23 included anywhere in the Safety Analysis Report prepared 24 by B & W prior to the TMI-2 accllent?

When you prepared this sentence did you 14 have in mind vital information that had not been 15 identified prior to the TMI-2 accident?

16 A

No, sir.

18 A

No, sir.

19 Q

Why was it desirable to have improved 20 equipment to recover a plant from unusual operating 21 situations?

22 MR. WISE:

Why was it desirable to have 23

- improved equipment.

I will object to the form 24 of the question.

25 If the witness wants to answer it he can.

O a

1 LaBelle 178 2

A I do not know that it is desirable, but that in 1 king to future plant. operation if there are l

any. equipment improvements that could be of value to 5

the plant operation, one would want to recommend 6

those.

Did you at any., time discuss any of the 8

items listed under " Actions" under Item-1 here in J

In what respect had the operating 12 experience involving the PORV at Davis-Besse been 13 misinterpreted?

14 A

Not referring specific.lly to Davis-Besse but 15 to the potential for failure of.a component such as 16 the -- the component operation such as the PORV should 17 hold some significance if it occurs more than one time.

in the follow-on operation of BA]W plants that it 5

would certainly be worthwhile to continue to look for 6

events which were recurrent and their importance.

7 Q

The second full paragraph on GPU Exhibit-N83 8

23 MR. GLASSMAN:

I don't think it is 24 harassing at all, Mr. Wise.

speaking in the future tense.

1 11 versus equipment reliability.

12 Q

Prior to the TMI-2 accident was $[(3N 13 focus in any. respect directed towards equipment

()

14 maintenance rather than equipment reliability?

15 A

There is an emphasis on maintenance of equipment (WY (0.&

16 through our nucleargor customer serviceAdepartment.

17 Q

Why is there an emphasis on maintenance 18 of equipment rather than equipment reliability?

19 A

My recommendation here is one of utilizing 20 the maintenance history more 'to further examine the 21 reliability of components that were being maintained 22 or replaced.

23 MR. GLASSMAN:

Was this consistent with'the design for 13 operation of the plants prior to the TMI-2 accident?

14 MR. WISE:

You know, 4

15 I have a real problem with proceeding this way i

16 with these continual jaunts into vague, i

17 ambiguous sorts of th. fugs, questions that i

j 25 Q

Mr. LaBelle, in the second indented v

l E

~

e--'_~_---

1 LaDollo 199 fh()

2 Paragraph under the heading " Action" there is a 3

sentence which reads as follows, referring to the 4

last sentence of.that paragraph:

~

5 "We should not be restrained from i

t i

6 hardware backfit."

7 What is meant by.the term " hardware 8

backfit."?

9 A

I think the reference here is to hardware 10 improvements being made on operating plants.

11 Q

What does the word "we" refer to in that 1

12 sentence?

((Ed) 13 A

As best I can recall,. Babcock & Wilco 5, O

]

14 Q

Was Babcock & Wilcox in any.way. restrained 15 from bardware backfit in the period prior to the 16 TMI-2 accident?

17 A

I think here you have to view this in a general 18 environment in which there are many recommendations 19 for hardware, operational or other improvements that 20 could be suggested by Babcock & Wilcox or any other 21 firm that is attempting to sell equipment or services 1

22 and that not all of those recommendations are accepted l

23 or purchased by a customer.

24 Q

With that background in mind, can you tell

()

25 us whether in the period before the TMI-2 accident

?

l

1 LaBelle 200 (pt)

Babcock & Wilcoxgwas restrained in any manner from 2

hardware backfit?

3 A

Not that I could say in the strictest sense, no, 4

sir, other than the fact that there were improvements 5

i r suggestions or recommendations that were not sold i

6 f

to our customers.

7 8

Q Were there improvements, suggestions or recommendations that were not sold to %]()Kcustomers j

g because of any. restraints.from hardware backfit?

10 3 I 11 A

In the same context as I have mentioned e

12 Previously, not that I am aware of.

13 Q

What did you mean by the word " restrained" 1 ()

14 in this sentence?

15 A

As best I can recall just in looking at the l

16 wording that is provided here, that of continuing to

]

17 look at operating experience, component reliability, P ant operations which may be of continued benefit and l

i 18 19 understanding for our customers.

20 Q

Was there a full-time organization within 21 B& W prior to the TMI-2 accident which was devoted to 22 Operating experience?

i 23 A

Not that I can recall m a full-time service i

24 that a customer had purchased, no, sir.

sir.

f 6

Q The next paragratih of GPU Exhibit-474

/

7 marked for identification reads as follows:

l 8

" Plant design and operation has been too i

9 rigidly. based upon conservative techniques and 10 supported by,a design bases which contain 11 highly. limited analytical work scope."

1 12 What is meant by,the term " conservative 4

l l

p 13 techniques"?

a i

14 A

Well, conservative technique is a phrase that 15 says that it is a conservative technique.

16 I don't understand your question.

l 17 Q

In what respe_ct are techniques conservative?

?

i fhose techniques are t

18 A

Just by assumptions that 19

' based on and the input;used in-those techniques.

4 i

20 Q

Were conservative techniques used by I

21 B(h[NinpreparingtheSARs?

l 22 A

In the context of the accident analysis i

(

23 submitted in the Safety Analysis Reports, yes, sir.

i l

24 Q

In what respect did the design basis for 25 plant design and operation contain highly limited t

n 1

LaBelle 202 2

analytical work scope, with particular emphasis on the O

3 word or words " highly. limited"?

4 A

I think to put the ent ire caragraph into

{

5 perspective for you, that the paragraph deals with t

6 analyses that have been provided for the licensing of 1

7 plants'via the accident analysis in the Safety Analysis Shh 8

Report and that would be beneficial to the nuclear 9

industry to have additional. analytical work done to 10 continue to improve upon the understanding of plant j

11 operation.

12 Q

In what respect was the analytical work 13 scope highly. limited?

14 MR. WISE:

I think he just answered that 15 question.

16 BY MR. GLASSMAN:

17 Q

Mr. LaBelle, what were the limitations upon

~

18 the work scope of the SAR's?

19 A

The limitations are the results of the work that 20

.is presented in the accident analysis of the Safety 21 Analysis Report.

22 Q

Aside from theslimited results, what did 23 you mean by " limited analytical work scope"?

24 A

Limited work scope is a part of the results of O

25 the accident analysis which was' referred to previously

1 LnBollo 203 l

A0 2

for the Safety Analysis Reporg.

s 3

Q

.What did you mean by the term " work scope"?

i 4

A Work scope is the -- is just what it says, the l

5 scope of the work presented in the Safety Analysis 1

6 Report, accident analysis.

1 7

Q Following the TMI-2 accident did you learn 8

that additional analytical work beyond that performed for the SAR's would be beneficial to the nuclear 9

10 industry?.

k 11 MR. WISE:

I will object to the form of 12 the question.

The witness can have a try at 13 answering that if he desires.

14 THE WITNESS:

Would you repeat the 15 question, please?

16 (The pending question was read by the 17 reporter.)

18 A

I believe in a general sense that analysis 19 following the TMI-2 incident which would. be helpful 20 in understanding the events which occurred or which 21 may.be of help to the industry in furthering the g

l 22 understanding of other events would be helpful to the l

23 nuclear industry.

I will qualify that by saying "but 24 not necessary."

25 Q

Are there any other qualifications you

n l

1 LcBollo 204 2

would like to make?

A No, sir.

3 I

4 Q

I would like you to refer to Page-4 o f.

5 GPU Exhibit-287 marked for identification.

Will you 6

tell us what you were referring to by.the words 7

"best estimata techniques" in the first sentence on 8

Page 27 9

A Best estimate in the context used here would be 10 referring to as close to actual as possible.

I 11 Q

How would that differ from bounding i

12 techniques?

13 A

Bounding techniques in the context used here 14 would be referring.to trying to provide a conservative 15 response in any.one or all results of the technique.

t.!

}

16 Q

After the number "4" on that same document 17 there is a sentence which reads:

18 "The analytical and hardware designers i

19 have become too separated from actual plant 20 operation response to transient conditions at 21 sites."

22 What were you referring to when you were-l l

23 referring to analytical and hardware designers?

24 A

To put this into the proper context, I would b\\

(,j 25 note that the analytical and hardware design ~ staff of

w.

at Babcock & Wilcox become too separated from actual I

I will permit the witness to answer that question, but I think that you are 9

it is a noun or a verb and I don't j

11 to whether 12 have the slightest idea which it is and I would 13 simply advise Mr. LaBelle that he can explain O-)

19 MR. WISE:

I think the word is " grammarian,"

20 but I could be wrong.

21 MR. GLASSMAN: We will call somebody.on 22 that, too.

MR. WISE:

I object on the grounds it is 8

a hypothetical question.

14 the witness to answer the question if he can.

15 A

It is very. difficult to discuss consequences 16 without knowing the specific scenario of events.

Had you ever considered the possible 18 consequences of a PORV set point drift such that a 19 reactor trip would fail to be achieved if the PORV 20 stuck open before the TMI-2 accident of March 28th, hkO3S8) 21 1979,7 i

22 A

I think you have to put this question into 23 perspec'tive with what we have.been discussing, that 24 prior to and up until the TMI-2 incident it was a

[ ( -)

25 practice to have the reactor trip set point above the s_

t T

E 1

LaBelle 232 hdd 2

set point for the electromatic relief valveAwhich

{/}

is the scenario that you have just referred to.

N-3 4

The purpose of putting the electromatic relief i

valve set point above the reactor -- high pressure 5

l 6

reactor trip set point was to reduce the likelihood 7

that one would have to face that scenario on a more 8

frequent basis.

9 Q

Prior to the TMI-2. accident was there 10 ever any. analysis conducted within BCi]p relating to i

11 set point drift which would result in a reactor trip i

12 failing to be achieved when the PORV stuck open?

Page-2 of GPU Exhibit-291 marked for identification O.

which refers to a development of a means to benchmark 3

Do you know if this was ever done?

i A

I think that this item as well as the other 6

items have to be put into the context that they are 7

Yes, sir.

g Q

What were those?

18 A

I just cannot recall the context in which they gg were conducted or the particular codes involv ed.

Q Has B & W ever investigated by its i

25 l

^'

4 A

There have been' studies conducted by B[q]W of 1

(qqhase) 5 two phase a irculation.

c 6

Q When were such studies conducted?

'I 7

A I do not recall specific tim.es that studies of 8

this nature were conducted.

9 Q

Were studies of this nature conducted (1903M) 10 before the TMI-2 accident of March 28th, 1979g I

l 11 A

There could have been studies conducted within

[l.06A) 12 the loss of coolant accidentAanalysis.

13 Q

Are you talking about the ECCS Unit?

O 14 A

Yes, sir.

{

15 Q

Are you aware of any studies of this 1

16 nature prior to the TMI-2 accident?

l 17 A

The loss of coolant accident will result in 18 two phase conditions as a part of the transient that

^

19 is examined, but I could not comment as to the 20 nature of the studies conducted.

21 Q

In other words, you do not know whether 22 those studies included consideration of whether 23 natural circulation could be' achieved under two phase 24 conditions; is that correct?

25 A

Since the analyses - -ay awareness of the

~

n

~~,

1 LaBolle 246 4

2 analyses is that adequate core cooling could be pr vided.

There was a form of ciulation that was 3

(a-plase)

't 4

provided for two phasdAconditions.

i The reason I say this is that it is 5

6 necessary,to understand the precise meaning that one 7

might provide to natural circulation in that it is 8

possible to have adequate core cooling and circulation 9

without natural -- what is normally termed natural i

10 circulation.

11 Q

I would like you to refer to Page -3 of 1

12 GPU Exhibit-191 for identification.

At the very

/~T 13 bottom of'.the page there is a statement after the 14 word " basis" that:

15 "NRC has shown concern that (3h]W does 16 not.have benchmarks supporting many of its code 17 Options and capability."

690cs) 18 Is it true that as of April 26th, 1979A i

l 19 B & W did not have benchmarks supporting many of its i

20 code options and capabilities?

21 A

I think that one has to put into perspective g

22 the benchmarks that had been performed with the 23 availability of operating plant information upon which 24 to base-those benchmarks.

11 Q

Is it true, then, that even in some j

We did not benchmark evedy. transient that 16 occurred in that there are many, transients that occur 17 during a given year.

We did have some benchmarks of 18 our -- of the codes that wers us'ed within the Safety 19 Analysis Unit.
